Abstract: 1329434 Modulating light RCA CORPORATION 6 Nov 1970 [6 Nov 1969] 52844/70 Heading H4F [Also in Division B7] A mirror of variable reflectivity, for example for day or night use in vehicles, comprises a transparent layer 36 of conductive tin oxide on a soda-glass substrate 20, a transparent dielectric layer 44 and a specular conductive layer 42 disposed on a glass substrate 22, and a nematic crystal layer 30 disposed between layers 36 and 44 so that when an A.C. or pulsed D.C. field applied across the crystal layer 30 via layers 36 and 42, it becomes light scattering, the layer 42 is obscured and reflection only occurs to a reduced extent at the surface of substrate 20 and interfaces of layers 20, 36 and 30. The maximum reflectivity of layer 42 in the visible spectrum is less than 75%. As described, two connections, 48, 49, are made to the layer 36 so that a current may be passed therethrough to heat the nematic layer 30, but such an arrangement may occur with either or both conductive layers 36, 42. The dielectric layer 44 prevents the nematic crystal from being affected by the voltage applied along the conductive layers, and also prevents the injection of electrons from the conductors into the crystal, which would reduce its lifetime. The layer 40 may be aluminium, nickel or gold for example, and the layer 44 aluminium oxide (by heating aluminium layer 40 in boiling water), mica, plastics or silica monoxide, dioxide or nitride. Layer 30 may be of anisylidene-p-aminophenyl-acetate. Preferred reflectivities and transparencies of the materials are stated.

Patent GB-1086699-A (GB)
Title: Improvements in or relating to cathode ray tube systems
IPC: G06F3/038
Filed: 1965-12-15
Abstract: 1,086,699. Cathode-ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec.15, 1965 [Dec.31, 1964], No. 53161/65. Heading H4T. The beam of a cathode-ray tube 26 (Fig. 1) is constrained to follow movement of a " lightpen " 25 over the tube screen by means of an arrangement in which a predetermined pattern of position defining spots (a), Fig. 6, produced on the screen is sensed by the " light-pen " which, when it senses at least one but not all of the spots, operates via control means to alter the position of the pattern in a direction such that all spots are sensed. If all spots or no spots are sensed no position alteration is effected and if the centre spot of the pattern is amongst those sensed-the sensing area of the " light-pen " being indicated by the circle of Figs. 6(a) . . . 6(f)-a smaller position alteration is effected than if the centre spot is not sensed. The spot pattern is produced by a circuit 46 (detailed in Fig. 4, not shown) which, under the control of pulses from a distributer 21, generates digital signals representative of the X and Y co-ordinates of the spots in a predetermined repeating sequence and these are then converted to analogue form in 47, 49 and supplied to a first deflection yoke 51. The sequence in which the spots are generated is also " set-up " in comparator/control circuit 23 and there compared with the signals sensed by the " light-pen "-supplied via amplifier 27 and lead 29-the result of the comparison being to provide signals which step-on a low order stage of X and Y position registers 31, 33 if the centre spot has been sensed or a high order stage if this spot was not sensed. The amount of beam deflection required is thus determined by the presence or absence of the centre spot from the light-pen and the outputs of the registers are then converted to analogue form in decoders 35, 37 and supplied to a second deflection yoke 45. Instead of a pattern of spots a pattern comprising a broken rectangle with a central dot may be employed (Fig. 6b).

Abstract: 1,093,220. Grinding. HOMFRAY & CO. Ltd. Nov. 15, 1966 [Dec. 18, 1965], No. 53753/65. Heading B3D. Apparatus for sharpening tufting-machine knives comprises a knife carrier 19 and a grinding wheel 25 mounted upon a stationary structure for rotation about parallel or slightly inclined axes with their peripheries overlapping, the knives 23 being secured to their carrier at angularly-spaced positions with their cutting edges projecting, and means being provided for continuously urging the carrier in an axial direction to press the knife-edges against the face of the grinding wheel. The carrier 19 is in the form of a flywheel mounted on a shaft 9 rotatable in the structure by a belt-drive 12 from a motor 10. One of the bearings for the shaft acts as the end 27 of a cylinder 28, the other end of which is keyed to the rod of a piston 31 engaging through a thrust race 33 a collar 34 on the shaft. Fluid pressure supplied through duct 35 urges the shaft to the left against an adjustable screw 36 so that the knives 23, which are secured in packs of 14 or 15 by straps 22 in inclined recesses in the periphery of the carrier are urged against the face 26 of the grinding wheel which is driven by a motor 24. During each rotation of the shaft 9, a pawl 42 is engaged with a ratchet wheel 43 on the screw 36 to rotate the screw a small amount and provide an increment of feed for each rotation of the carrier. During rotation of the carrier, the knives may dip into a tank of coolant. A bellows 44 protects the bearing 8 for the shaft.

Title: Fan Assembly of Variable Air Delivery Type
IPC: F04D29/36
Filed: 1967-12-05
Abstract: 1,180,595. Axial-flow fans; cooling engine cylinders. AISIN SEIKI CO. Ltd. Dec. 5, 1967 [Dec.7, 1966], No.55377/67. Headings F1B and F1C. A vehicle engine cooling fan comprises two adjacent and relatively angularly adjustable bladed discs 30, 35. The discs each have the same number of blades which are preferably all of the same form and have the same peripheral pitch and inlet angle. The rear disc 35 is fixed to the driving shaft 62 via a hub 37, while the front disc 30 is mounted to the shaft via a hub 32 and a coarse screw thread 68, 69 so as to be angularly adjustable about the shaft. A thermostat 59 exposed to the engine cooling water in the water pump housing 65, has an element which expands on reaching a predetermined temperature, e.g. 85C., to move rods 59a, 55 leftwards and thereby cause the hub 32 and front disc 30 to move around the shaft against the act ion of a spiral spring 43. Guide rods 41 and arcuate slots 42 limit the angular adjustment of the front disc 30. The disc 30 is adjustable from an engine-cold position in which the blades thereof completely overlap the blades of the rear disc 35 to render the latter blades ineffective, through intermediate positions, to an engine-hot position in which the blades of the front disc 30 are symmetrically arranged between the blades of the rear disc 35 so that all of the blades are fully utilized. In an alternative embodiment, the thermostat and its associated components are omitted, the front disc is fixed to the shaft, and the rear disc is mounted to the shaft via a ball bearing so as to be angularly adjustable relatively to the front disc by the aerodynamic loading on the blades in accordance with speed. The arrangement is such that the front disc is adjusted from the fully effective blade position to the overlapping blade position as the engine speed increases from a predetermined value, e.g. 3000 r.p.m., to a maximum value, e.g. 6000 r.p.m. The fan may incorporate the features of both embodiments described.
